3D Design G22 / G23 4-Series M-Sport Carbon Rear Diffuser
AVAILABLE TO ORDER
The 3D Design G22 / G23 4-Series M-Sport Rear Diffuser redefines the lower rear of the G22 Coupe and G23 Convertible with a quad-exit diffuser design engineered to complement the M-Sport rear bumper. The shape draws the eye across the full width of the rear fascia, introducing purposeful structure and depth to a chassis that responds well to OEM+ aerodynamic refinement.
The 2x2 Carbon Fiber weave (CFRP) construction delivers a gloss clearcoat finish that highlights the weave beneath, with OEM-level surface texture and consistent factory-style fitment.
Designed and manufactured in Japan, 3D Design components are developed with a focus on fitment precision, durability, and real-world usability. Their approach blends motorsport influence with street functionality, resulting in aerodynamic upgrades that enhance both form and function without sacrificing practicality.
